XO Security

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A declining trend compresses what a buyer would pay.

   タイトル通りです。AIOS等の定番プラグインと比べると機能は少ないですが、必要最低限の対策が揃っており設定が非常にわかりやすいので使いやすいです。これだけでは不安という人はBBQ Firewallを併用すると良いです。

   長年、SiteGuardを使っていましたが、たまにログインできなくなってプラグインをサーバーから削除とかしたりだったので、こちらのプラグインを使い始めました。 設定画面もわかりやすく、作動も安定していて、ログイン試行履歴とかも見れます（結構不正ログインされようとしているのがわかって楽しい）、随時他のサイトのセキュリティプラグインもこちらに切り替えていこうと思っています。感謝感謝
